Corbet married William Pitt’s eldest sister, Harriot, according to her nephew, the 1st Lord Camelford, ‘one of the most beautiful women of her time, but little produced in the great world, and died very young from anxiety of mind in consequence of a foolish engagement she entered into with Mr. Corbet ... to whom she was privately married’.
A man of some financial ability, Corbet was one of three M.P.s on the board of the Royal African Co. who piloted the company’s petition concerning their forts through the House against the opposition of the free traders to Africa in 1729-30.
